(Springer Verlag, 2018)El Romeral is one of the largest iron oxide-apatite (IOA) deposits in the Coastal Cordillera of northern Chile. The Cerro Principal magnetite ore body at El Romeral comprises massive magnetite intergrown with actinolite, ...
-
(Elsevier, 2020)Magnetite is the most important iron ore in iron oxide-apatite (IOA) deposits which represent the Cu-poor endmember of the iron oxide-copper-gold (IOCG) clan. Magnetite chemistry has been used as a petrogenetic indicator ...
-
(Elsevier, 2016)Platinum-group element (PGE) and gold inclusions are usually present in peridotites and chromitite deposits associated with ophiolites. Here, we present the first detailed study of the mineralogy of precious metals in ...
-
(Elsevier Ltd, 2019)The San Luis Formation is one of the lithostratigraphic units constituting the early Paleozoic crystalline basement of the Sierras de San Luis, which are part of the Sierras Pampeanas of central Argentina. The low-grade ...
-
(Elsevier, 2017)Catfish Genidens barbus is a commercially fished species from the south-western Atlantic Ocean. Overfishing of this species during the last few years has caused a collapse of fisheries and in turn has led to a ban of its ...
-
(Elsevier, 2020)The Valle Fertil-La Huerta batholith is a differentially tilted, compositionally stacked, calc-alkaline plutonic sequence in the central Famatinian arc of Argentina. It consists of two major lithologic units: these are (1) ...
-
(Elsevier Ltd, 2019)© 2018 Elsevier LtdThe ratio of the halogens F and Cl in apatite is highly sensitive to changes in the composition of an evolving silicate melt or aqueous fluid. For this reason apatite chemistry is widely used as a monitor ...
-
(Soc Economic Geologists, 2020)Porphyry Cu-Mo deposits (PCDs) are the world’s major source of Cu, Mo, and Re and are also a significant source of Au and Ag. Here we focus on the world-class Río Blanco PCD in the Andes of central Chile, where Ag is a ...
-
(Elsevier, 2017)The purpose of this paper is to assess the use of multi-elemental otolith fingerprints as a tool to delimit catfish Genidens barbus fish stocks in four estuaries from the southwestern Atlantic Ocean. Barium:Calcium (Ca), ...
-
(Taylor and Francis Inc., 2020)U-Pb detrital zircon age patterns are presented for nine samples of metapelites from the metamorphic basement of south-central Chile between 37° and 40°S, along with detrital zircon ages for a sample from the Piedra Santa ...
-
(Elsevier Ltd, 2019)Mass transference from lower to upper crustal levels requires an efficient network of pathways that act as channels for draining melts from the source and transferring magmas through the crust. We report on a mid-crustal ...
-
(E Schweizerbartsche Verlagsbuchhandlung, 2017)Humite minerals, including Ti-rich, hydroxyl-dominant chondrodite and clinohumite, occur in Paleozoic antigorite serpentinite in the La Cabana area, in the Chilean Coastal Cordillera (similar to 38 degrees 30'S- 73 degrees ...
-
(Springer, 2020)Kiruna-type iron oxide-apatite (IOA) deposits constitute an important source of iron and phosphorus, and potentially of rare earth elements (REE). However, the origin of IOA deposits is still a matter of debate with models ...
-
(Elsevier, 2017)The ultramafic massifs of the Serrania de Ronda (namely Ronda, Ojen and Carratraca) are portions of Proterozoic (similar to 1.2-1.8 Ga) subcontinental lithospheric mantle (SCLM) affected by partial melting and infiltration ...
